世界自行车所有权下坡

Bicycle ownership around the world is declining amid rising wealth levels and increased use of motorised vehicles in developing countries, a study has found.

Four out of ten households on the planet own a bike, according to a paper based on surveys from 150 countries between 1989 and 2012. But the growing popularity and affordability of motorised运输研究人员说，，例如汽车和踏板车，“没有分散自行车的使用”。

自1992年以来，中国尤其经历了自行车所有权率的崩溃，当时有97％的家庭拥有自行车。但是，这项研究表明，到2009年，这一数字降至63％，在大多数其他国家 /地区的所有权率平坦或下降。

在多哥，自行车所有权在1998年至2010年期间一直保持稳定，占约34％的家庭，但在巴拉圭的所有权率从1996年的57％的家庭下降到2002年的39％。

这些趋势可以预期，因为过去十年中每人的机动车数量增加了，以“人类历史上从未见过”，尤其是在中国，印度和非洲的部分地区。the World Bank’s全球道路安全设施在美国。

The纸，发表在运输与健康杂志去年12月,发现自行车所有权是金属氧化物半导体t common in developed countries such as Denmark and the Netherlands, where around four-fifths of households have at least one bike. But in West, Central and North African countries, bicycles are more uncommon, with less than a fifth of households owning one, the study says.

While motor vehicles are often well documented, this study is the first to gather global data on bicycle ownership, the researchers say. Understanding bike numbers could help governments in developing countries devise bicycle-friendly政策that promote better health, less congested cities, safer roads and cleaner air, they add.

The researchers spot wide disparities within regions and several outliers. Peru and the Philippines were found to have extremely low bicycle ownership rates compared with their neighbours. In contrast, Burkina Faso in West Africa is the only non-European country in the top tier, with 84 per cent of households owning a bicycle in 2010.

According to the researchers, this is due to the country’s investment in cycling infrastructure and a “positive attitude” towards cycling among the population.

“Compared to its surrounding countries, Burkina Faso has an astonishingly high level of cycling infrastructure such as physically separated bike lanes or road lighting for cyclists at intersections,” says lead author Jimi Oke, a civil engineer at Johns Hopkins University in the United States.

While cycling patterns are well studied in countries such as China and the Netherlands, the study sheds light on other interesting countries — such as Burkina Faso — that have been less studied, Oke adds.

“We can learn from what happens elsewhere and it’s better to have a bigger pool to widen the evidence base for policy,” he says.
